OpenGL: Made non-power-of-two textures support configurable by a cvar, gl_texture_NPOT, disabled by default: Fixes serious slowdown on some old graphics hardware, such as R300 to R500 class Radeons on Mac OS X, which the driver is lying about its capability.

Sound: The client no longer tries updating the ambient sounds when not connected, ie. when no map is active.

Hammer of Thyrion is a port of Raven's Hexen2 source code and is based on the original Linux Hexen II project, Anvil of Thyrion.
